The applied pressure is illustrated in the first graph.

The second graph shows the measured output voltage of the sensor. The deviations between the predicted values derived from the exponential function and the measured values induced by a pressure change are shown in the third chart. Finally, an integration of the deviations is plotted in the last chart.

It can be seen that the voltage progress is proportional to the applied pressure. To provide a stable solution for a pen and touch tracking, it is preferred to combine the above described foil design with an additional dot pattern, as provided, for example, by ANOTO RTM.

The pen and touch separation is realized through software-based processing. A combined input driver analyses both pen and touch input data synchronously. Whenever a new touch is performed, the input driver waits for about 50 ms for a pen input at the same spot within a small threshold.

During this period, all touch data gets temporarily stored in the input driver. Whenever a pen input is noticed, the input driver forwards only the pen input and ignores the touch input. Otherwise, the temporarily stored touch data gets regularly forwarded to the applications. In an embodiment, the sensing device or the present inventoin is used to implement HMI. The HMI technology based on the PyzoFlex technology has the potential of providing touch-input functionality in a low-cost process by printing over large-areas on flexible substrates, optionally with nearly transparent electrodes.

In am embodiment, the basic element of the HMI technology is an array of printed ferroelectric sensor capacitors based on the semicrystalline ferroelectric polymer PVDF- TrFE as the dielectric sandwiched between transparent or IR-absorbing electrodes.

The sensor is sensitive to changes either in pressure due to its piezoelectric nature or in temperature due to its pyroelectric nature. Such printed capacitive sensor array can be integrated monolithically with organic transistors and display elements and further be utilized as a flexible, easy processable, low-cost user interface that can be controlled either by touch or by proximity non-touch.

All layers can be deposited by screen printing. In an embodiment, a new membrane button concept is provided. In particular, the printed piezoelectric polymer can serve as a pressure sensor for inputs and as an actuator for tactile feedback, but also as a loudspeaker enabling acoustic feedback.

As the input device of the present invention is printed, the rigidity of the backbone substrate in combination with the adhesion of the printed PVDF-TrFE affects the vibrational output of the sensor device. This is illustrated in Figure 9. The result is a simple input key with passive haptic feedback based on pressure induced deformation of the keypad which induces charges at the electrodes attached to the active polymer.

The final impression of the feedback given to the user can be freely designed for any purposes and surroundings. The intensity of the feedback signal can be determined by the design of the backbone, the size of the keypads and the signal sent to the sensor. Moreover, it is desirable to optimize the sound response and acoustic pressure of a speaker without effecting the overall key design and functionality.

A preferred embodiment comprises the fabrication of dome-shaped PVDF sensors with optimized stiffness for radiating acoustic waves at specified frequencies and sound levels.

For a piezoelectric multi touch panel, the electrode pattern according to an embodiment of the invention is either an array type with the resolution being limited by the printing process or a triangular type based on a low conducting laminar electrode with higher resolution. Array type multi ' touch panel. In an embodiment of the invention there is provided a multi- touch panel based on a true piezoelectric sensor, especially generated by a low-cost, printable polymer paste.

The embodiments described above can be used for fabricating large area, printed multi- touch sensors for different kinds of user interactions. Since the ferroelectric polymer is transparent in the visible range, it can also be used for fabricating touchscreens by means of transparent electrode materials.

For reliable triggering of single touch-points, an arraylike structure of orthogonally ordered bottom and top electrodes forming piezoelectric active, capacitive areas at the overlapping regions is provided. However, when multi touch gestures are to be captured, the generation of ghost points due charge distribution described by the Kirchhoff s laws becomes difficult in a single layer approach.

In an embodiment of the invention, this problem is addressed not by using a combination of complex and costly electronics and software as, for example, it is done in connection with prior art capacitive touchscreens. This design allows the. This is illustrated in Figure In another embodiment of the invention there is provided a triangulation based. In this embodiment the signals are detected in the corner of the sensor foil and due to a distance-dependent decrease of the sensor signal, being related to the series resistance of the low-conducting electrode, the exact location of the excitation point can be calculated.

By using the sensor structure related to the multi- touch panel as described above, local changes of heat can be detected as well. In combination with suitable processing means, spatially resolved changes of heat can be recorded and analysed.

This technology can be used for the cost efficient fabrication of active laser safety walls, for example for automated laser welding systems or in the vicinity of automated laser fabrication systems exceeding a certain laser class.

For those applications, the thermally sensitive sensor-foil included in the sensing device of the present invention is attached to a passive laser housing typically consisting of a metal plate of appropriate thickness for forwarding the heat generated by a defocused or scattered laser beam directly to the sensor array.

Processing means are provided to decide if and which kind of hazardous event occurs and to initiate an alarm or shut down the laser system if necessary, depending on the signal distribution and amplitude. This also enables an easy replacement of damaged parts after a hazardous event. Further, the spatial resolution of the sensor sheets allows for simplified error diagnostics since the intensity and position of the temperature rise can be revealed by the processing means.

Energy harvester. Because of these characteristics, the sensor can be employed as an energy converter which converts mechanical and thermal energy to electrical energy.

Preferably, the design of the capacitive energy harvester is adapted to the existing surrounding. In particular, the thickness of the active polymer affects the current to voltage ratio and the size of the active area to be excited relates to the amount of generated charge.

For example, using a single HMI-sensor with an area of 0,7 cm 2 , 3nC can be generated in a single touch event.

By adapting the sensor design, the generated energy can be used, for example, to bias a wireless sensor node within a wireless sensor network in an industrial automation surrounding or any appropriate appliance in the context of ambient assisted living.

Intelligent Floor. The sensing device of the present invention is capable of detecting vibrations over a wide frequency spectrum. Accordingly, the sensing device can be used as a microphones, a solid bone sound sensor, or as an acceleration sensor.

In the context of ambient assisted living e. In an embodiment of the invention, the sensing device is attached to a surface, for example the walls or floor of a room in a building. The acoustic sensitivity of the sensing device can be tuned to a certain frequency band by varying its size, shape and thickness. In the field of security applications, certain events e. In the growing field of ubiquitous computing in daily surroundings ambient assisted living , one aspect of growing interest is the "intelligent floor" US 8,, B2.
